Why Miami Shores Homeowners Choose CGI Windows & Doors

Winslow Windows & Doors provides CGI Windows & Doors in Miami Shores, FL, repairing and replacing everything from Sentinel double hungs to Estate Collection picture windows. We’re not a CGI factory arm and we’re not authorized by them. We’re a local crew that has worked on hundreds of CGI units across the village since 2011, so we diagnose the actual failure instead of reaching for the brand playbook. If your CGI window is binding, fogged, or leaking salt air, call (727) 483-7883 and Ed Winslow or one of our techs will talk you through what’s actually wrong.

CGI built its name on Miami-Dade County NOA Impact Windows services ratings. In Miami Shores, that matters twice over: the village sits in the High Velocity Hurricane Zone, and the Architectural and Historical Review Board won’t approve just any impact unit on a 1930s Mediterranean Revival home. Homeowners need a product that clears both hurdles. CGI’s narrow-profile aluminum lines, especially the Sentinel Series with simulated divided lights, are one of the few product families that routinely do. That’s the dual-compliance reality our crews navigate on nearly every Miami Shores job.

Why Trust Winslow Windows & Doors for Your CGI Windows & Doors?

Our techs have spent years inside CGI products, and it shows in how fast we find the problem. We know which Sentinel single hungs bow in salt air, which Estate Collection insulated glass units fog first, and which Targa slider rollers seize after one storm season near Biscayne Bay. That’s not catalog knowledge. It’s ladder-and-flashlight knowledge, earned on Miami Shores homes built from hollow clay tile and early concrete block, where anchoring a modern impact frame takes more than a standard buck and some shims.

Ed Winslow learned building science at Miami Dade College’s Wolfson Campus and has spent the better part of three decades installing and replacing windows and doors across Miami-Dade. Miami Shores has been home base the whole time. He grew up a few blocks from Barry University and still gets his morning coffee on NE 2nd Avenue. His name is on the truck and the invoice, so every CGI job, whether it’s one fogged sash or a whole-house full frame replacement, gets the same attention. We’re independent CGI service providers, which means we recommend what the house needs, not what a manufacturer’s warranty department prefers. And every Winslow job carries the Done Right Promise: if it’s not done right, we make it right.

Common CGI Windows & Doors Problems We Fix in Miami Shores

Here’s what we actually see on CGI products in this village, street by street, season after season:

• Warped or bowed sashes on Sentinel single hung windows. The Sentinel Series is a workhorse in Miami Shores because its narrow aluminum profile clears AHRB review on Mediterranean Revival homes. But older Sentinels, especially east-facing ones, develop bowed sashes from years of thermal cycling and salt-air exposure. The sash binds halfway up the track, air leaks through the weatherstripping, and the owner stops opening the window entirely. We replace the warped sash, swap the block-and-tackle balances, and re-pin the locks.
• Fogged insulated glass units in Estate Collection fixed and picture windows. Estate Collection windows look right on Mission-style Miami Shores homes, but their larger glass panes put more stress on the inner seal. When that seal fails, moisture gets between the panes and the glass fogs permanently. Cleaning won’t fix it. The glass unit has to come out and a new sealed unit goes in, which we do without disturbing the frame.
• Roller alignment and track corrosion on Targa horizontal sliders. The Targa Series sliders are popular in Miami Shores sunrooms and patio openings. The problem here is mechanical: salt-laden air off Biscayne Bay corrodes the roller assemblies, and debris builds up in the bottom track. The door gets harder to push every month until someone forces it and bends the roller bracket. We clean, realign, and replace the roller assemblies, and we always check track level while we’re at it.
• Stripped lock keepers and sagging hinge corners on Craftsman casement windows. Craftsman casements take a beating in storms, and we see two failures repeatedly in Miami Shores: the lock keeper strips out of the aluminum frame after years of hard cranking, and the hinge corners sag from the weight of the sash plus salt corrosion. Both are repairable. We drill, tap, and install new keepers, and we rebuild the hinge corners with factory-spec hardware.
• Failed weatherstripping and sealline gaps on all CGI lines. This is the silent one. The weatherstripping on any CGI unit degrades faster on east-facing elevations in Miami Shores because the persistent onshore airflow carries salt straight into the seallines. Owners notice a warm draft or a whistling sound during afternoon storms. We replace the weatherstripping and reseal the perimeter, which usually restores the window’s air and water performance without replacing the sash.

On a 1960s Miami Shores bungalow, our tech found two CGI Sentinel double hungs with bowed sashes that were binding halfway up and letting in hot, salt-laced air. We replaced the warped sashes with factory-milled units, swapped the worn block-and-tackle balances, and re-pinned the sash locks. The owner now opens those windows with one hand, and the air-leak test came back clean.

CGI Parts & Our Repair-vs-Replace Approach

We use OEM CGI parts whenever they’re available: balances, locks, weatherstripping, rollers, keepers, and hinge hardware. Factory fit is factory fit, and on impact-rated units, the last thing we want is a part that doesn’t match the NOA assembly. When OEM lead times stretch past two weeks, we tell you before we touch anything. We’ll name the aftermarket component we’re using and why it’s the right call. A silent slider in July beats waiting out hurricane season with a gap.

Our repair-vs-replace math is simple. If the frame is square and the glass is intact, we repair. If the sash is warped beyond re-hanging, the track is pitted, or the frame has water damage from years of failed seallines, we price a replacement honestly. We don’t sell replacements for repairable windows, and we don’t patch windows that should come out. That’s the whole approach. Call (727) 483-7883 and we’ll tell you which side of the line your window falls on.

Our CGI Service Process - Step by Step

1. 1
   Diagnosis. We inspect the unit in place: sash alignment, balance tension, roller condition, weatherstripping compression, sealline integrity, and frame square. For CGI impact units, we also verify the glass and frame markings against their Miami-Dade NOA documentation. You get a written line-item diagnosis before any work starts.
2. 2
   Repair or install. We order OEM CGI parts if available, or call out the aftermarket option in writing if lead times don’t work. For full frame replacements in Miami Shores, we remove the old unit down to the rough opening, address any hollow clay tile anchoring issues, install the new CGI frame with proper flashing, and square everything before fastening.
3. 3
   Test. We operate every sash or panel through its full range of motion, run an air-infiltration check where applicable, and inspect seallines from both sides. On impact units, we verify the assembly matches the NOA specs. If anything doesn’t pass, it gets corrected before we leave.
4. 4
   Warranty and follow-up. Every repair and install is covered under our Done Right Promise. If something isn’t right, we come back. That’s not a marketing line. It’s the standard Ed Winslow has run the business on since 2011.

CGI Products We Service & Install in Miami Shores

We service and install the full CGI lineup we see across Miami Shores: Sentinel Series single hungs and double hungs, Estate Collection fixed and picture windows, Targa Series horizontal sliders, and Craftsman Series casement windows. We stock common OEM CGI hardware locally: balances, rollers, lock keepers, weatherstripping, and hinge assemblies. That means most repair jobs don’t wait on a factory shipment. For replacements, we order factory glass and frames to spec and handle the full frame replacement from tear-out to trim.

We Also Service These Brands

Cgi in Hollywood and beyond is a big part of our Miami Shores work, but it’s not the whole picture. We’re authorized installers for PGT, CWS, ES Windows, and ECO Window Systems, among others. That matters because some Miami Shores homes mix brands, and we’d rather service everything on the house than tell you to call someone else for the patio door.
